Title: Automatic gain control circuit
Inventor: IKEMOTO NAOMICHI
IPC: H04N5/52
Filed: 1984-07-31
Abstract: PURPOSE:To perform starting value type gain control operation and keyed type gain control operation in combination through one comparing circuit by amplifying a luminance signal on the basis of the head of synchronism through a couple of differential amplifiers whose emitters are connected mutually through a resistance, and using the differential amplifiers which differ in gain distinctively between a burst gate period and other periods. CONSTITUTION:A differential amplifier circuit 13 is connected between a luminance and chromaticity separating circuit 4 and a comparing circuit 13. The collector output of the transistor (TR) Q2 of the differential amplifier circuit 13 is applied to the inverted input terminal of the single comparing circuit 12 in the burst gate period, and the collector output of TRQ3 is applied in other periods. In this case, let R3=R4 and R5=R6, and further R1<R2, and the gain of Q2 is larger than that of Q3. If a synchronizing signal deforms or if a video signal exceeding a prescribed input value is inputted, the voltage of a video signal part rises above the synchronizing input voltage Va of the comparing circuit 12 except during the burst gate pulse period and a starting value type gain control circuit lowers the gain of an amplifier circuit 2. Here, the prescribed level is determined on the basis of the gain difference between Q2 and Q3 so that the starting value type gain control circuit operates.

Title: Controlling method for position of strip in side trimming line
Inventor: TEZUKA SAKAE
IPC: B65H23/02
Filed: 1979-12-10
Abstract: PURPOSE: To minimize the strip trimming margin by employing the two-stage controlling method in which both the positions of the uncoiler and the side trimmer are varied.  
     CONSTITUTION: When the position of the uncoiler 1 is controlled, only a large displacement is absorbed by the control output m 1  which is proportional to the square of the first displacement amount x 1  and a small displacement is neglected (the control is stopped). Therefore, when the position of the side trimmer 4 is controlled, the remaining small displacement amount x 2  is absorbed. Said method permits a remarkable improvement in the comprehensive controllability to the positions of the uncoiler 1 and the side trimmer 4. Accordingly, the strip trimming margin largely decreases.
